Body suit & Onesie

Bodysuits are one-piece garments for babies. They don’t have legs and will usually include a closure (ie buttons or snaps) at the nappy area to help hold the nappy in. They are snug and not loose-fitting.

Onesies are loose-fitting, one-piece garments that cover the torso and end above the waist with buttons or snaps for closure over the crotch area. They sometimes have legs. The key thing here is they’re not snug on the body and they’re loose-fitting.
